ATTACHMENT FOR CHECK-WRITERS.

Specification of Letters Patent.

Application filedAugust 19, 1915. Serial No. 46,394.

To all whom it may concern Be it known that 1, JOHN B. DENNIS, a citizenof the United States, residing at Ottumwa, in the county of Wapello andState of Iowa, have invented certain new and useful Improvements inAttachments for Check-Writers; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in selectorattachments for check writing machines and consists in the provision ofa simple and efiicient attachment to a checkwriter to facilitate thesetting of the type to print certain words, numbers or characters.

The present invention comprises various details of construction,combinations and arrangements of parts which will be hereinafter fullydescribed, shown in the accompanying drawings and then specificallydefined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of a check writer showing my invention asapplied thereto. Fig 2 is a side elevation. Fig. 3 is an enlarged topplan view. Fig. 41 is a bottom plan view of a part of the apparatus.Fig. 5 is a sectional view taken on line 55 of Fig. 3, looking in thedirection of the arrow. Fig. 6 is a sectional view on line 66 of Fig. 3.Figs. 7 and 8 are detail sectional views, partly in elevation, of meansfor releasing a part of the selector device. Fig. 9 is an enlargeddetail view of a tilting member forming a part of the selector mech-'anism. Fig. 10 is a detail View of a selector bar, and Fig. 11 is amodified form.

Reference now. being bad to the details of the drawings by numeral, 1designates the frame of a checkwriter of the rotary type, to which aslotted plate 1 is fastened, and 2 designate a shaft journaledlongitudinally in the frame, mounted in suitable bearings therein andhaving a gear wheel 3 at one end in mesh with a gear wheel 4 fixed tothe shaft 5, having a crank handle 6, and its other end has a beveledgear 7 which is. in

mesh with a gear 8 fixed to the shaft 9 which is journaled in suitablebearings in the bracket arm 10. A second bracket arm, designated bynumeral 11, is mounted upon the other end of the frame and carries ashaft 12 in suitable bearings about which a grooved pulley 13 isjournaleol, and a sprocket wheel 14: is fixed to the shaft 9/ Pins orteeth 15 project from the circumference of the sprocket wheel, and 16designates an endless tape or band, made preferably of metal and havinglugs 17 projecting therefrom at intervals, the distance between the lugsbeing preferably equal to the circumference of the sprocket wheel uponwhich they are mounted.

A yoke, designated by numeral 18, is attached to the carriage 19 andwhich carriage actuates the type of the checkwriter, not shown, andwhich forms no part of the present invention, and an arm 20 projectingfrom said yoke extends through a slot 21 in the split tubing 22 and acoiled spring 23 bears at one end against the face of the arm 20 and itsother end'against the end of the tube in which it'is mounted, thepurpose of said spring being to normally hold said yoke and carriage atits farthest limit at starting position in one direction. Said yokecarries a latch 24, a detail view of which is shown in Fig. 9 of thedrawings, and which is mounted upon a pivotal pin 25 passing through theaperture 26 and which pin is mounted upon a laterally projecting portion18 of the yoke, as shown clearly in Figs. 5 and 6 of the drawings. Acoiled spring 27 is mounted in a recess in the upper edge of the yokeand bears against one end of the latch and tends to hold the same in theposition shown in solid lines in Fig. 6 of the drawings.

Upon reference to Fig. 9 of the drawings, it will be noted that saidlatch has a rectangular outlined opening 28 formed therein for thereception of the contracted end 29 of the lateral projection 18 of theyoke. The extreme free end of the latch is bent at an angle forming acam projection 24*, pro. vided for a purpose which will be hereinafterdescribed.

Upon reference to Fig. 6-of the drawings, it will be noted that theupper edge of the lateral projection 18 of the yoke has a recess 30adapted to receive the band 16 and projecting. from the under surface ofthe projection 1 8 is a roundedplfiojection 31, I

. sprocket wheel and pulley, serving to cause the carriage to be movedforward. A pawl 32 is pivotally mounted upon a pin 33 carried by saidyoke and extends through a slot 50 in the plate 1*, as shown clearly inFigs. 5 and 6 of the drawings,'a'nd turns idly in one direction and isprevented from tilting in'the'opposite direction by its upper end comingin contact with the edge of the yoke upon which it is mounted. Selectorbars 3% are mounted side by side and adapted to have slidinglongitudinal movements, as shown in Fig. '3, and each bears a numeral orword as shown and the outer end of'each is preferably provided with arecess 39 adapted to receive an instrument to facilitate 'the' pushingin of the bar to theposition shown inFig. 3, so that the inner end ofsaid selector bar will be positioned in the path of the pawl 32, saidprojecting por tion of the bar serving as a 'stopto arrest the returnmovement of the carriage "after the' pawl upon the yoke has passed by,turningidly overf the'b'ar as the carriage is driven forward by theendless band on the sprocket wheel.

Springs, designated by numeral 40, are fastened at corresponding ends tothe angled bars 41 fastened to the plate l and to the pins 4-2, saidpins being secured-to the selector bars at and guided in the slots 43 InFig. 11 of the drawings, I have shown a slight modification, in whichthe selector bar 45 is provided'with a hole 47in which an instrument maybe inserted, forming means whereby said selector barmay be movedlongitudinally independent of the spring.

In operation, the operator by pushing in upon one or another of theselector bars may cause its inner end to project beyond the others andin the pathof the pivotal latch and cam projection upon the latter.'

This being done, the operator by giving the crank a revolution may causethe sprocket wheels to rotate through the medium of the endless bandmounted thereon and, as a lug 17-comes in contact with the marginal edgeof the latch, it will cause the carriage and the yoke secured thereto tomove forward. When the pivotal pawl 32 comes in contact with theprojecting end of the selector bar, which is held at its farthest limituntil after the carriage is actuated to its limit in one direction, saidyoke will turn idly, al-

lowing the pawl to pass the projecting end of the selector bar and thecam projection uponthe latch coming in contact with the selector barwill cause the latch to tilt to j allow the lug upon the band to pass bythe latch, thus releasing the yoke from the lug upon the band and thecoiled spring 23 will tend to return the carriage toward its startlngposition but lts movement will be arrested by the pivotal pawl 32 comingin contact with the selector bar which is held in its path. Theapparatus thus being set for printing of the desired numeral or wordupon the check, upon the completion of the turning of the crank handle.The selector bar is then released, if held by a spring at its farthestforward position or withdrawn if the modified form shown in Fig. 11 isemployed, and the spring which is attached to the carriage will returnthe same to its starting position.
